MACHlNE FOR OPENING, CLEANING, AND GINNING SEED-COTTON.

SPECIFICATION forming part of Letters Patent No. 383,754, dated May 29,1888.

Application filed October 8, 1887. Serial No. 251,848.. (No nodohl Toall whom it may concern.-

Be itknown that I, Joan E. Mormons, a citizen of the United States,residing at An burn, in the county of Cayuga and State of New York, haveinvented certain new and useful Improvements in Machines for Opening,Cleaning, and Ginning SeedOotton, of which improvements the following isaspeciticat-ion.

My invention more especially relates to that class of machinery fortreating seed -c0tton known as the rollergin.

The first part of my invention relates to the method of feeding theseedcotton from the Its object is to open the cotton'boll as it passesfrom the ho'ppee and draw out its iiber, soas to facilitate itssubsequent treatment. This end I attain by combining with the hoppertraversing teeth or hooks and a card having a vibrating or reciprocatingmot-ion relatively to the teeth or hooks, which organization preventsthe clogging of thebollsin said hopper and withdraws, separates, andspreads outits fibers.

The next part of my'invention relates to the manner of cleaningthesced-cotton as itpasses from the hopper, to which end my improvementconsists in combining with the hopper, traversing teeth, andreciprocating card a roller provided with wings or heaters revolving inproximity to but more rapidly than the teeth, so as to beat'out dust andother impuri ties. This roller also serves to clear the trav ersingdrawing-hooks above mentioned.

My improvement further consists in combining with the hopper, traversingdrawing teeth, reciprocating card, and clearing-roller, above mentioned,a laterally reciprocating grating arranged beneath the teeth andclearing-roll, upon which grating the scedcotton falls on its way to theginning apparatus, and through which grating the dust and otherimpurities drop.

The next partot' my invention relates to the mechanism for feeding thesecdcotton to the ginning-rolls, and for ginning it, to which end myimprovement consists in combining rollers, ofany suitable material ofcomparati vely small diameter, rotating in close proximity to eachother, between which the ginned cotton passes,

with a feed roller arranged parallel therewith containing parallellongitudinal radially-reciprocating ribs, which are alternately thrustout to seize and carry the cotton to the rolls at a regulated speed, andthen are retracted to allow the seed cotton to pass freely to the rolls.By this means the feed-roll is enabled to run close to the ginningrolls,and to avoid drawing the cotton away from the rolls.

My invention further consists in combining with the ginning-rolls andfeed-roll, above described, seed-separating teeth reciprocatinglongitudinally in the bite of the rolls, parallel therewith, to detachthe seed from the lint as the latter is drawn through the rolls.

My invention further consists in combining with the ginning-rolls,feed-roll, and reciprocating teeth a guide-plate partially encirclingthe feedroll and in such relation thereto as to enable theradially-reciprocating ribs to properly seize, hold, and deliver theseed cotton to the ginningrolls.

My invention relates to further details and organization of theapparatus employed, hereinafter described, and designated in the claimsat the end of this specification.

The accompanying drawings represent all the improvements herein claimedas embodied in one apparatnsin the best way now known to me. Some ofthem, however, may be used without the others, and in machines differingin their details of construction from those herein described.

Figure 1 represents a plan or top view of my improved machine; Fig. 2, aside elevation thereof; Fig. 3, a longitudinal central section andelevation thereof on the line 3 3 of Fig; 1. Fig. 4 is a similar sectionthrough the feeding and ginning mechanism on the line -14 of Fig.

1, on an enlarged scale. Fig. 5 is a perspective view of the feedrollerwith parts broken away. c Fig. 6 shows perspective and sectional viewsof the clearing and seed-removing teeth; and Fig. 7, a transversesection through the feedroller, showing the cam which reciprocatesitsblades, ribs, or teeth.

That portion of the machine into which the seed-cotton is fed I call thefront of the machine,the other part the rear. That side on the left ofaperson facing the front part of the machine I call the left side, theother the IOO right.

The mechanism is shown as mounted in a main frame, A, of suitablematerial and wellknown construction. The seed-cotton is contained in ahopper, B, open at top and in the rear, but closed on its other sides,the front end of which is preferably inclined backward and downward, soas to cause the seed-cotton naturally to be fed backward toward the ginning apparatus. The lower rear part of the hopper is closed by a seriesof traversing teeth, 0, in thisinstance shown as mounted on a roller, 0,revolving in suitable hearings in the frame, the teeth beingslightlyinclined forward in the direction of their rotation, which issuch that they traverse from the bottom toward the top of the hopper.The function of these teeth is to draw, open, or spread the bolls, topre vent their being fed to the rollers in lumps or masses, and tofacilitate the subsequent operation of cleaning. This operation isfacilitated by suspending a card, D, in or about the line of the hopperand above the rear of the draw ing-roller, which card retains and drawsout the bolls, preventing them from being carried forward in a mass. Toprevent the clogging of this card, a short reciprocating or vibratorymovement concentric with the axis of the drawing-roller G is imparted toit. This is represented as accomplished inthis instance by mounting thecard on radial arms D, pivoted on the axis of the drawing-roller andvibrating said arms by a crank and pitman from a counter'shaft, It. Ashield, D, is pivoted at its upper end, (i to the frame, its lower endbeing loosely connected with the reciprocating card, so as to vibratewith it. The function of this shield is to prevent matter being thrownover back of the card by the drawing-roller. The seed-cotton, afterbeing thus separated and drawn out by the action of the card anddrawing-roller, is carried round by the latter until it comes in contactwith a beater, E, consisting of a roller provided with wipers e, andmounted in a frame on an axis parallel with that of the drawing roller,preferably of smaller diameter and revolving at a higher rate of speed,so as not only to beat, sweep, or clear the seed-cotton from the teethofthe drawing-roll, but to beat out dust or other impurities which dropdown through a grating,F, arranged beneath it. This grating consists ofparallel bars or rodsf, inserted longitudinally of the machineina'frame,to which a laterallyreciprocating motion is imparted inwellknown ways, as hereinafter described. The bars are inclined fromfront to rear, so as to gradually feed the seed-cotton to theginningrolls. A suitable casing or shield,G, prevents dust and lint frombeing thrown out by the beater.

A stationary guide or concave, H, preferably of metal, is secured to theframe underneath the rearward portion of the reciprocating grating,inclined backward and downward, and extends underneath the feed rollerI, around the lower part of which it concentrically curves. Thisfeed-roller is mounted in suitable bearings in the frame, revolvingparallel and in close contact with the ginningrolls. Its details ofconstruction are shown in Figs. 3, 5, and 7. It is shown in thisinstance as provided with eight radial slots, in which ribs or bars Ireciprocate freely transversely to its axis, these bars being connectedby cross-pieces i, so that as a bar is protruded on one side of theroller it is correspondingly retracted on the other. This movement iscffected by a suitably-constructed cam, 1, secured to the frame near theedge of the roller, and bears against the inner sides of the projectingends of the ribs. As the roller revolves, the ribs are successivelyprotruded on one side of the roller,while the ribs on the opposite sideare retracted. The retraction of the ribs is effected by thecross-pieces 1' ,which connect opposite ribs, so that as one rib isprotruded it draws with it or retracts into the body of the roller theopposite rib. The shape and relative position of thecam I are shown inFig. 7.

Ginning-rollsJJ, made of anysuitable wellknown material, are arranged torevolve parallel with and close to each other and to the feed-roll I,the latter, however,being above the line of nearest approximation of thetwo rollers.

I have used disks of leather arranged side by side and compressed so asto form rollers with good success. A roller similarly constructed ofrawhide disks would also'answer a good purpose.

The ginning-rollers are intended to revolve in contact with eachother,but are mountedin bearings Z. (Shown by dotted lines in Fig. 4.)The bearing-blocks are pi'efe rabl y mounted on elastic cushions 2, soas to give the blocks a slight play for the passage of the lint whenrequired. The rollers are preferably made of comparatively smalldiameter. One of them at least should not'exceed five-eighths of an inchin diameter. Undue springing or yielding of the rollers is prevented byintermediate anti-friction bearings, Z, at suitable intervals.

The yielding bearings and the anti-friction devices are of well-knownconstruction and need no further description. These ginning-rollersshould run at a much higher speed than the feed rollers say ten orfifteen times as fast.

A series of ginning or seed-extracting tceth, 7c, are shown as mountedon a plate or bar, K, reciprocating laterally with its teeth or pointsin close approximation to the bite of the ginning-rollers, as shown inFig. 4. The preferred form given to these teeth is shown in Fig. 6. Theyare preferably made about threequarters of an inch from center to centerand with about five-eighths of an inch aperture, with their pointscomparatively sharp or chisel-shaped,andsomewhatbroaderthantheir necks,to conform to the bite of the rolls, into which they should enterdeeply. They are slightly undercut, as shown-in the sectional part ofFig. 6, so as to tend to ride over and press down the seed withoutcutting them.

I will now proceed to describe the gearing V herein shown, but do notlimit my claims to the specific organization represented, as that may bechanged in various well-known ways without departing from the principleof my invention.

A drivingshaft, Z, mounted in suitable bearings in the frame, carries apulley, L, driven by a belt from any suitable motor. A spurgear, L, onthis shaft drives a corresponding gear, j, mounted on the axis of thelower ginning-roll. A corresponding spur-pinion, L on the right hand oropposite end of the driving-shaft,engages with an idle-wheel, U, whichin turn drives a spur-wheel, J", on the righthand end of the upperginning-roll, by which means the rolls are caused to revolve in oppositedirections. A small pinion, m, on the driving'shaft meshes with a largespur-gear, M, mounted on the right-hand side of the frame on ashortshaft, M, which carries on its inner end a small spur-gear, M whichengages with a corresponding pinion, M on the shaft of the feed-roll I.Under the organization described the ginning-rolls traverse with equalspeed at their points of contact,wl1atever may be their relative size,while a much slower motion is imparted to the feed-roll, which traversesabout twelve times slower than the ginning-rolls. The ribs of thefeed-roll are reciprocatedfat suitable intervals by cams 1, secured tothe frame near each end of the roller. The details of the roller areshown in Figs. 4 and 7. The reciprocating teeth it are mounted on a bar,K. A bar, K, rigidly connected with this arm, extends downward andforward, its end reciprocating in a guideway, it, in the frame. This armis driven by a pitman, If, and a crank, a, mounted on a shaft, n,carrying a bevel-gear, U, meshing with a bevelpinion, N, on thedriving-shaft. A belt, Z, from a pulley, O, on the main shaft encirclesa pulley, O, on a counter-shaft, 0, in the front of the frame. A smallpulley, p, on the counter-shaft 0 by means of a cross-belt,p, drives acorresponding large pulley, P, on the shaft 0 of the roller 0, thusgiving it the required rotation. A pulley, R, on the shaft 0, by meansof a belt, R, drives a corresponding pulley, r, on a crank-shaft,connected at each end by a pitman, R", with the radial arms D of thereciprocating card, to give it the proper motion. A pitman, S, ispivoted at one end to the band-wheel O on the eounter-shafto and at theother to a bell-crank, 8, connected by a connectingaod, f, with thelaterally-vibrating grating F, to give it the required movement. A belt,t, passing around the inner side of the large band-wheel O on thecounter-shaft 0, drives a pulley, e, on the beater-shaft eflto give itthe required movement.

The arrows indicate the direction of the movement of the various partsof the gearing.

The following is a description of the operation of the machine.Seed-cotton fed into the hopper is seized by the traversing teeth on theroller 0 and carried upward underneath the reciprocating card D, whichtends to open out ceptacle.

the bolls and spread the material over the roller in a thin layer, whichis carried around until it comes under the operation of therapidly-revolving beater E, which beats out dust and other impurities,clears the seed-cotton from the teeth on the rolls G, and throws it downupon the vibrating grating F, down which it slides, and drops into thespace between the concave and the feed-roller I. The latter is soarranged, asdeseribed, that at this portion of its movement its bladesare protraded in moving downward, carrying the seedcotton with them atadefinite rate ofspced, and at the same'time preventing it from travelingfaster than the blades. As the latter push the seedcotton into the biteof the seed-rolls, they are retracted and move up out of the way,leaving the space clear. The reciprocating rake or teeth k playunderneath and in rear of the rear part of the concave, and seize theseed as the lint is drawn through between the ginning-rolls, which seeddrop down in the space between the teeth, and are conducted to anysuitable receptacle. The ginning-rolls, moving more rapidly than thefeedroll, tend to draw the fibers away from the seeds, which are thusthoroughly cleaned by the conjoint operation of the feed-roll, thereciprocating teeth, and the ginning-rolls. The lint, after passingthrough the ginning-rolls, slides down an incline, U, to any proper re-A guard consisting of a blade, V, arranged with one edge parallel withand close to the upper ginning-roller, prevents lint from being carriedup and wound around the rolls in that direction.

I have obtained good results by reciprocat ing the rake or ginning teethonce to each revolution of the rolls with short staple cotton; but therelative velocity of the ginningrolls and rake should be variedaccording to the length of the staple. For instance, the longer thestaple the slower the rake movement, and vice versa.
